Mutual epithelial-mesenchymal interaction represents a fundamental control mechanism during the development of organs and tissues. This review article demonstrates the importance of such interaction for tumor formation where it influences the biological properties of cancer stem cell and tumor itself.
The teratoma and melanoma are employed as examples to demonstrate the influenceof embryonic microenvironment on the biological properties of tumor, mainly on its potential to metastasize. The manipulation of cancer microenvironment represents the perspective therapeutic tool for cancer treatment in future
